Not sure why this was posted here, but this is one of Caesar's greatest victories in the Gallic wars. The engineering capabilities of the Roman legions were very impressive. For those who don't know, Caesar had built a wall around the city of Alesia to blockade the defenders in. When a relief force was dispatched to attack the Romans and break the siege, Caesar built another wall and line of defenses to hold off the attacking relief force. The Romans were able to defeat the Gauls and add it to the Roman Empire (Republic).
